<a name="l00080"></a>00080 <span class="keyword"> The OpenCores aoOCS SoC is a Wishbone compatible implementation of most of the Amiga Original Chip Set (OCS) and computer functionality.</span>
<a name="l00081"></a>00081 <span class="keyword"> </span>
<a name="l00082"></a>00082 <span class="keyword"> aoOCS is not related in any way with Minimig - it is a new and independent Amiga OCS implementation.</span>
<a name="l00083"></a>00083 <span class="keyword"> </span>
<a name="l00084"></a>00084 <span class="keyword"> <h3>Features</h3></span>
<a name="l00085"></a>00085 <span class="keyword"> - The aoOCS SoC contains the following Amiga/OCS components:</span>
<a name="l00086"></a>00086 <span class="keyword"> - blitter</span>
<a name="l00087"></a>00087 <span class="keyword"> - copper</span>
<a name="l00088"></a>00088 <span class="keyword"> - system control (interrupts)</span>
<a name="l00089"></a>00089 <span class="keyword"> - video: bitplains, sprites, collision detection</span>
<a name="l00090"></a>00090 <span class="keyword"> - audio: 4 channels, low-pass filter</span>
<a name="l00091"></a>00091 <span class="keyword"> - user input: PS/2 mouse, PS/2 keyboard and joystick (keyboard arrow keys)</span>
<a name="l00092"></a>00092 <span class="keyword"> - floppy: read and write ADF files directly from a SD card. Only the internal floppy drive is implemented</span>
<a name="l00093"></a>00093 <span class="keyword"> - 8520 CIA</span>
<a name="l00094"></a>00094 <span class="keyword"> - ao68000 OpenCores IP core is used as the aoOCS processor</span>
<a name="l00095"></a>00095 <span class="keyword"> - All of the above components are WISHBONE revision B.3 compatible</span>
<a name="l00096"></a>00096 <span class="keyword"> - The aoOCS contains the following additional components:</span>
<a name="l00097"></a>00097 <span class="keyword"> - SD card controller written in HDL with DMA. Supports SDHC cards only.</span>
<a name="l00098"></a>00098 <span class="keyword"> - 10/100 Mbit Ethernet controller written in HDL to send the current VGA frames (frame grabber)</span>
<a name="l00099"></a>00099 <span class="keyword"> - HDL drivers for SSRAM, PS/2 keyboard, PS/2 mouse, audio codec, VGA DAC</span>
<a name="l00100"></a>00100 <span class="keyword"> - aoOCS uses only one external memory: a SSRAM with 36-bit words and pipelined access. A video buffer with about 250KB is located SSRAM. Another 256KB are used by the ROM. All the rest memory</span>
<a name="l00101"></a>00101 <span class="keyword"> can be used as Chip RAM.</span>
<a name="l00102"></a>00102 <span class="keyword"> - The On-Screen-Display is implemented in HDL as a finite state machine. No additional controller/processor with firmware required to handle the SoC.</span>
<a name="l00103"></a>00103 <span class="keyword"> - The following options are available on the On-Screen-Display:</span>
<a name="l00104"></a>00104 <span class="keyword"> - select ROM file to load (only Amiga Kickstart v1.2 was tested)</span>
<a name="l00105"></a>00105 <span class="keyword"> - enable or disable Joystick (keyboard arrow keys)</span>
<a name="l00106"></a>00106 <span class="keyword"> - enable or disable floppy write protection</span>
<a name="l00107"></a>00107 <span class="keyword"> - insert a floppy - select one from a list</span>
<a name="l00108"></a>00108 <span class="keyword"> - eject an inserted floppy</span>
<a name="l00109"></a>00109 <span class="keyword"> - reset the system</span>
<a name="l00110"></a>00110 <span class="keyword"> - The On-Screen-Display is independent of the running Amiga software. It is enabled and disabled by the Home key and controled by the keyboard arrow keys and the right CTRL key.</span>
<a name="l00111"></a>00111 <span class="keyword"> - Only PAL timings are implemented. </span>
<a name="l00112"></a>00112 <span class="keyword"> - The video output is VGA compatible: 640x480 at 70 Hz. A rather simple method is used to extend the 256 PAL horizontal lines to 480 VGA lines: all lines are doubled except for every 8th one.</span>
<a name="l00113"></a>00113 <span class="keyword"> - The system uses generally a single clock: 30 MHz. There are two more clocks: 12 MHz, 25 MHz generated to interface with external hardware (Audio codec, Ethernet controller). A single altpll is used</span>
<a name="l00114"></a>00114 <span class="keyword"> to generate all three clocks from one 50 MHz external clock. More information about clocks is available at \ref page_spec_clocks.</span>
<a name="l00115"></a>00115 <span class="keyword"> - A VGA frame grabber is implemented that sends captured frames by 100 Mbit Ethernet in IP/UDP packets. </span>
<a name="l00116"></a>00116 <span class="keyword"> - The system uses about 26.400 LE on Altera Cyclone II and about 267.000 bits of on-chip RAM.</span>
<a name="l00117"></a>00117 <span class="keyword"> - The blitter functionality was tested against the E-UAE Amiga software emulator.</span>
<a name="l00118"></a>00118 <span class="keyword"> - Tested only on a Terasic DE2-70 board (www.terasic.com.tw).</span>
<a name="l00119"></a>00119 <span class="keyword"> - Documentation generated by Doxygen (www.doxygen.org) with doxverilog patch (http://developer.berlios.de/projects/doxverilog/). The specification</span>

<a name="l00136"></a>00136 <span class="keyword"> <h3>Limitations</h3></span>
<a name="l00137"></a>00137 <span class="keyword"> - No filesystem support on the SD card. Data is read from fixed positions. The contents of the SD card is generated by the <tt>aoOCS_tool</tt> described at \ref page_spec_operation.</span>

<a name="l00139"></a>00139 <span class="keyword"> - All bitplain data is fetched at once in a burst memory read at the begining of each line. No changes to the bitplain data done after the beginning of a line are visible.</span>
<a name="l00140"></a>00140 <span class="keyword"> - Currently aoOCS requires an 36-bit word SSRAM to store the video buffer. This way 3 pixels 12-bits each can be stored in one word.</span>
<a name="l00141"></a>00141 <span class="keyword"> - Serial port not implemented.</span>
